Abstract
This paper describes a metallographic investigation of the influence of tungsten or molybdenum additions upon the transformation and precipitation reactions occurring in Co-rich Co-Cr alloys. It is shown that tungsten has little effect upon the α-β transformation temperature range, while molybdenum tends to raise it. Both elements tend to promote the formation of γ phase, molybdenum being more potent in this respect than tungsten.
